Fuel Injection Harness Questions? 89 TBI setup

[1972C10]

I have an 89 C1500 W/T With a 305/Th375 Im thinking about parting For the harness and a few other items

Question: Is How easy will it be to put this in an 85 C20 With a 350/Th400 It has a Rebuilt 350 Thats pretty much stock with the exception of an RV Cam

I was thinking about getting this Pump And putting it in front of my Dual Tank Selector Mallory 60FI

I was also thinking about using the trans kickdown off the fuel injection harness I bet its controlled by the TPS and Ecu I figure if it doenst act right i can always hook the factory Kickdown thats hooked to the gas pedal back up.



I have 350 injectors As well Im told that is the only difference between the 305 and 350 setup.

And if i was to want to buy a Chip for it would i buy one for a 305 or a 350?


I have acess to a 87 454 Tbi adaptor that goes onto the Q-jet intake and has water pass trough it

Its either that or slot a Tbi intake to fit my 882 heads Or put TBI 191 Swirl Ports The Engine I really dont want to do that unless i absolutley have to Since i only have 4000 miles on the heads since rebuild.
